#' Spellmans Yeast Cell Cycle data
#' From this study "Comprehensive Identification of Cell Cycle–regulated Genes of the Yeast Saccharomyces cerevisiae by Microarray HybridizationD"
#' by Spellman et al.
#' This microarray dataset is a comprehensive catalogue of yeast genes whose transcript levels
#' change periodically withinthe cell cycle. We use σ-factor based synchronisation data that containsexpression ofS. cerevisiaegenes sampled over 18 time points.
#' We filter out 786 genes from the entire genome, as those genes that have demonstrated consistent oscillating changes within the yeast cell cycle in Spellman et al.(1998).
#' This dataset has been copied from the Supplementary Materials of Lebre et al. paper "Inferring dynamic genetic networks with low order
#' independencies"
